NAME¶

thin_restore - restore thin provisioning metadata file to device or file.

SYNOPSIS¶

thin_restore [options] -i {xml file} -o {device|file}

DESCRIPTION¶

thin_restore restores thin provisioning metadata created by the respective device-mapper target dumped into an XML formatted (see thin_dump(8)) file, which optionally can be preprocessed before the restore to another device or file. If restored to a metadata device, the metadata can be processed by the device-mapper target.

This tool cannot be run on live metadata.
